Subject: [PATCH 5/8] mm, pagevec: Remove cold parameter for pagevecs
Date: Wed, 18 Oct 2017 08:59:49 +0100
Message-ID: <20171018075952.10627-6-mgorman@techsingularity.net> (raw)
In-Reply-To: <20171018075952.10627-1-mgorman@techsingularity.net>

Every pagevec_init user claims the pages being released are false even in
cases where it is unlikely the pages are hot. As no one cares about the
hotness of pages being released to the allocator, just ditch the parameter.

No performance impact is expected as the overhead is marginal. The parameter
is removed simply because it is a bit stupid to have a useless parameter
copied everywhere.
